These openings also provide for the supply of air for combustion. floor of the third hearth contains a chainln this furnace too, the l ber -fin which air circulates, communieating at both ends, with the exterior, as is si .vn by Fig. 5, for the purpose, likewise, of keeping it as cold as possible, to avoid the decomposition of the carbonate of calcium of the gangue, which is on it.

What l claim and desire to secure by Letters Patent is l. A sulfur burner comprising a plurality of internal hearths disposed one above the other, means for introducing the orc into the center one of the hearths, the lloor of such hearths being provided internally with channels for the passage of cold air, the upper hearths constructed for the completion of the combustion and the lower ones for the extraction of the ashes, and means for introducing air into the combustion cham ber to be heated in said lower hearths.

2. A sulfur burner comprising a plurality of hearths, one of which is provided with a loor of greater thickness and strength and comprising a chamber for the circulation of air, said chamber being open to the atmosphere, means for introducing ore into a hearth above the lowermost one, and rabbles rotatably mounted above and below the lowermost floor and having downwardly extending teeth. y

3. A sulfur burner comprising a plurality of hearths, one of which 1s provided with a therefrom or conducting the ore to a hearth above the bottom, rabbles rotatably mounted above and below the lowermost floor and having downwardly extending teeth, and a vertically disposed shaft carrying said rabbles, there being a central opening through said floor for the passage of the gradually burning material downwardly at the center.

4. A sulfur burner comprisin a casing, a plurality of internalvhearths isposed one above the other, the floor receiving the heavy mineral being thicker than the other, means for introducing the ore upon such floor, means for introducing air to cool said thickened floor andinsuring a circulation to prevent decomposition, and a vertical flue communicating with said air. introducing means to create a vertical draft.

5.
